ID 2.1.1.396 DE cephaeline 6'-O-methyltransferase. CA cephaeline + S-adenosyl-L-methionine = emetine + S-adenosyl-L- CA homocysteine + H(+). CC -!- The enzyme IpeOMT1, isolated from the roots of the tropical plant CC Carapichea ipecacuanha, catalyzes the final step in the bionsynthesis CC of the alkaloid emetine. CC -!- A second enzyme isolated from the same plant, CiOMT1, also catalyzes CC this activity, but catalyzes the activity of EC 2.1.1.395 with a much CC higher activity.
